Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to improvements in automatic lighting control devices such as timer-controlled lighting devices.

In recent years, in order to prevent unnecessary lighting from an energy-saving perspective, many devices have been introduced, such as lighting timer control and daylight usage control, to intensively control lamp blinking and brightness increase/decrease.

However, in such a device, it may be inconvenient to suddenly turn off or dim the light.

For example, in a timer-controlled factory, if there are overtime workers and the timer is accidentally set to turn off the lights 15 minutes after finishing work, the lamps will suddenly go out while the overtime workers are working, which is very dangerous. This will cause inconvenience.

The purpose of this invention is to alleviate the above-mentioned disadvantages.

FIG. 1 is a block diagram showing an embodiment of this invention, in which 1 is a lighting device consisting of a plurality of lighting devices, 2 is a setting section that has a key switch and sets a control pattern for the lighting device 1, and 3 Reference numeral 4 indicates a clock generation section that generates pulses at a constant cycle, and 4 indicates a processing section composed of a microcomputer using an atto program method. , 4b
, equipped with 4C.

5 is the blinking control signal output to the terminal 4a and the terminal 41)
A drive unit 6 controls the lighting device 1 to blink and increase/decrease the brightness in accordance with the light increase/decrease control signal outputted to the terminal 4C.The drive unit 6 controls the lighting state of the lighting equipment, current time, etc. This is a display section for displaying information.

Although only one line for each of the output terminals 4a and 4b is shown for convenience, a line is provided for each appliance (or group of appliances).

In such a configuration, when the current time is read into the processing section 4 by operating the key switch of the setting section 2, the current time is displayed on the display section 8 by internal program processing, and the clock generation section 3 Counting of input pulses starts, and first the clock time is set.

Next, by operating the key switch of the setting section 2, a timer setting which is a control pattern is performed.

In other words, a series of time programs are sent to the processing unit 4, such as at what hour and minute (timer time), what number of fixtures in the lighting device 1 are to be turned on, and at the next timer time, how many other fixtures are to be dimmed. Let it read.

When the timer setting as described above is completed, the timer operation is started next.

In other words, the computer in the processing section 4 always compares and matches the current time and timer time, and if they match, sends a control signal corresponding to the appliance number and control details to the terminal 4a.
or 4b, and the driving unit 5 controls the illumination device 1 according to the time program.

The above is the control operation which is the main operation of this device.Next, the advance notice operation according to the present invention will be explained.

For example, let's say that the number 1 appliance is to be turned off at 5:30 pm, and a notice is given five minutes in advance.

In that case, the same as the above timer operation (current time + 5 minutes)
A comparison operation is always performed between the timer time and the timer time, and if they match, it is immediately checked in the processing section 4 whether or not the No. 1 fixture is lit.

When it is confirmed that the lighting is on, the processing unit 4 generates a notice signal to the terminal 4b, which foretells that a control signal for controlling the lighting of the first appliance to be turned off will be output to the terminal 4a in 5 minutes.

Figure 2 is a timing chart showing such an operation.
Figure a shows the flashing control signal of terminal 4a, Figure shows the warning signal, Figure C
indicates a change in the lighting status of the lamp of the first fixture.

Further, the t3 timing is the timer time when the No. 1 appliance is turned off, the t1 timing is the time when the lighting of the No. 1 appliance is confirmed and a warning signal is generated, and the t2 timing is the time when the warning signal ends.

In this case, the warning signal has a frequency of IHz and a frequency of 50
%3 pulses.

When this advance notice signal is input to the drive unit 5, for example, the phase control circuit causes the lamp of the No. 1 fixture to repeat the state of dimming and full light three times as shown in Figure C.

As a result, even though there were overtime workers, it was accidentally posted at 5:03 p.m.
Even if a program is set to turn off the light at 0 minutes,
By dimming the lamp three times, overtime workers can know in advance that the lamp will turn off in 5 minutes, and can take appropriate actions such as resetting the program, alleviating the inconveniences of conventional equipment. I can do it.

Fig. 3 is a flowchart 1 showing the routine for generating the above-mentioned warning signal, and comparison operation 7 detects 5 minutes before the generation of the control signal.
, Operation to check the lighting status of designated equipment 8, Operation to generate a warning signal 9
, and a warning signal confirmation/stop operation 10.

In the above embodiment, a notice is given that all lights will turn off, but depending on the purpose of the lighting device 1, it may be possible to give a notice of appropriate control such as all lights → dimming, dimming → lights out, or light distribution. can.

Especially in this case, the warning is given by lighting lamps, so
It has the advantage that there are almost no oversights.

As described above, this invention has the effect that, since it is forewarned in advance that the control will be performed by a change in the lighting state of the lamp of the lighting device, if there is an inconvenience due to the above control, it is possible to take appropriate measures.
